I tried to play a bit with multistep forms since it looks as the only
system to have $form_values back into the form generating function.

So the form function change it's output according to the received
$form_values.
I know _validate get called, but it seems that form_set_values()
inside _validate has no effect on the values received by the form
generating function.

Not that I really need to use form_set_value... but just for better
understanding of how things work...

Another thing I don't need now but that is out of my understanding is
how to succeed in getting the $form_values in the form generating
function *and* execute the _submit hook.

If the form is multistep, it doesn't fire the _submit hook so I'd be
curious to know how you could have the $form_values *and* fire the
_submit without the need to load what you submitted from the
DB/session/whatever.

thx
